What It Is and How It Works
Ivermectin belongs to the class of medications known as antiparasitics. It exerts its effects by binding to specific chloride channels within the nerve and muscle cells of parasites, leading to increased cell membrane permeability. This results in paralysis and death of the parasites or cessation of their maturation. Notably, ivermectin does not kill adult worms but rather disrupts their ability to reproduce.
Indications / Uses
The primary approved uses of ivermectin include the treatment of infections caused by:
- Onchocerca volvulus, the cause of river blindness (onchocerciasis).
- Intestinal strongyloidiasis caused by Strongyloides stercoralis.
- Certain types of scabies and lice infestations, though these uses can vary by region.
While ivermectin has been considered for various off-label uses, these should only be pursued under direct medical supervision and with up-to-date guidance from healthcare professionals.

- Pregnant or breastfeeding women, in whom usage may be restricted.
You must follow your healthcare provider’s instructions regarding the appropriate dosing.
How to Take It Correctly Step-by-Step
